Both on the left side had to be towed is horribly scary on another incident about three weeks prior. The gas pedal broke while she was getting off the freeway and braking trying to brake with part cars during rush-hour. The car is going and braking at the same time she had to go up on the curb come to find out the gas pedal broke off and lunged hinged itself between the brake and the gas pedal so when she was trying to break, the car was accelerating at the same time scared her to death. She’s almost [XXX]. She bought this car and I almost killed her twice Not to mention all the issues we’ve had going into the shop six weeks at a time three different dealerships we’ve only have the car in our possession maybe two months out of the eight months they’ve done nothing and they can’t fix it.
